Danny DeVito and Rhea Perlman are separating after 30 years of marriage, their publicist told TheWrap.

DeVito, star of "It's Always Sunny in Philadelphia" and Perlman, star of "Cheers," have three adult children together. They appeared together in the classic sitcom "Taxi," and their company, Jersey Films, has produced films including "Man on the Moon" (about their "Taxi" castmate, Andy Kaufman), "Pulp Fiction," and "Erin Brockovich," among many others.
